Now, with publication of a study by investigators at the Cedars - Sinai Board of Governors Regenerative Medicine Institute, ALS researchers know the effects of the attack are worsened, at least in part, by the aging and failure of support cells called astrocytes, which normally provide nutrients, housekeeping, structure and other forms of assistance for neurons.
«Since cholesterol is required by neurons to form synapses (connections) with other cells, this decrease in cholesterol could affect how nerves function for appetite regulation, behavior, memory and even pain and motor activity,» says Dr. Kahn, who is also Mary K. Iacocca Professor of Medicine at Harvard Medical School.

Alzheimer's disease, the most common form of dementia, is characterized by the accumulation of plaques (composed of amyloid - beta protein) and fibrous tangles (composed of abnormal tau) in brain cells called neurons.
In motor neuron disease, it was caused by mutations in the FUS protein itself which meant it was no longer able to change form.
When the researchers modeled the effects in mice, they found it strengthened the connections between neurons that make learning possible — what is known as synaptic plasticity — by increasing the action of a cell receptor critical to forming memories.
An intriguing clue to this selectivity is provided by Setola et al., who identify a truncated form of SMN1 that arises from an alternative spliced SMN1 transcript that is preferentially expressed in the axonal projections of developing motor neurons.
